According to the Environmental Working Group, a research and advocacy group based in Washington, drilling companies are side-stepping a permitting requirement for the use of diesel fuel in their fracturing fluids by using similar petroleum distillates that contain the same toxins as diesel, but require no permitting.

The report also cites evidence that drilling companies continue to inject diesel fuel underground without the proper permits.

WASHINGTON — The Environmental Protection Agency on Wednesday proposed the first national standard for emissions of mercury and other pollutants from coal-burning power plants, a rule that could lead to the early closing of a number of older plants and one that is certain to be challenged by the some utilities and Republicans in Congress...

Lisa P. Jackson, the agency’s administrator, said control of dozens of poisonous substances emitted by power plants was long overdue and would prevent thousands of deaths and tens of thousands of cases of disease a year.

Ms. Jackson pointedly included the head of the American Lung Association and two prominent doctors in her announcement to make the point that the regulations were designed to protect public health and not to penalize the utility industry.

Public health advocates said utilities had delayed the rules for more than two decades with court challenges and lobbying campaigns.

“If you think it’s expensive to put a scrubber on a smokestack, you should see how much it costs to treat a child over a lifetime with a birth defect,” said Dr. O. Marion Burton, president of the American Academy of Pediatrics, who stood with Ms. Jackson in announcing the rule.

Oddly, when the story first ran, it included an account of how Ms. Jackson invited a group of second graders from a nearby elementary school to the announcement. Earlier today, Mar. 17, it was edited out. Was it Broder and Rudolf, or the Times? Are children not newsworthy?

"She invited a group of second graders from a nearby elementary school to attend the rule’s unveiling at her agency."

I found a mention of it in a cached Google listing.

Why did the Times delete it? The article as it first appears will always be located here. (PDF). The Google cache will expire as soon as you read this. See for yourself, read between the lines.
